QThe track trip ,14 operates tllG'SWltCll points 2 and 3 when rolling stock approachesthe switch fromthje pivoted ends 8 of the switch points;

A pair of I ing arms-23 and 24 is plvotally mounted at adjacent ends as at 25 centrally of the cross ties 7" with the arms 23 and 24 angularly directed towards the free swinging ends of the switch points; A bracket. 26 carried by the cross ties 7 F pivotally supports as at 27, a cross arm 3 28, and a longitudinally shifta'ble operating'rod 29 guided in a bearingBO upon as, illustrated with the adjacent ends of the arms 28 pivoted thereto the operatingrods 29 having an angled forward end providedwith a pin and lot connection; 32 with the outer end of the switch point operating arm 23.

' Rolling stockon the track comprising the rails 1 and 4and travelling-in the direction of the free swinging ends of the switch points 5 and 6, should it be desiredto shift the switch points from the full line positions shown in Figs; land 3 to the dotted line position shown in Figure 8, manually controlled abutments 60 carried by' the rolling stock 'areloweredfor engagement with the triplevers 41 and 56, the operating rods 37 and 51 being longitudinally'shifted for moving theouter end of the switch point operating arm 24away from the switch-point 6 "andby the provision-ofthe cross arm connection 45lbetween' the operatingrods 51 and 47, the latter operating rod is shiftedin the reverse direction to position the trip lever 59 for subsequent operation of a following train if desired Actuation of the trip-leve'rf41 move's'the operating'rod 37 andby its pivotarm connection 28' with the operating rod 29," the latter is shifted in a reverse direct-ion" for moving the, switch point operatingarm 23 into engagement with'the switch point, 5 to move the saniefinto engagement with' the rail" 1 as shown by dotted lever 34in opposite position to be engaged v by a following train if desired together with the trip lever49 "The abutments' 60 carried by the r'olling'stock' are manually lowered into engagement with the desired ones of the trip levers, the position fof the switch points relativefto the track rails land 4 being de- 'termined in advance'bythe semaphore signal elements 21 @2122; Should the switch points :5 and 6 be in" the full fposition shown in Figure 2 and it is desired to shift to dotted line position illustrated in said figure, abutments 60 carried by the rolling stock are lowered for engagement with thetrip leve r s 34 49 and thereverse 5 operation" of the' mechanism is eifected,

In order to clear either one of'th'efrails 1on4 ofthe'free' swinging ends of theswitch ing arms 14 carried gaged by a wheel W of points 5 or 6 when rolling stock approaches the switch in a'direction from the pivoted ends of the switch points, either of the operatby the shaft 10 is enthe rolling stock as will become evident from an inspection of Figures 9 and 10, the depression of either one of the trip arms 14 causing rotation of the shaft 10 carrying the same tocause the arm 12 upon such shaft to shift the tie bar 9 to move the switch points 5 and 6 away from the rails. The trip levers 34, 41, 49 and 56 are operated by rolling stock approaching the switch points from their free swinging ends thereof while the trip arms 14 are operated by rolling stock approaching the switch from the points.

From the above detailed description of the invention, it is believed that the construction and operation thereof will at once be apparent, and While there is'herein shown and described the preferred embodiment thereof,

pivoted ends of the switch be made in the details of construction; such as will fall within thescope of the invention as claimed.

I claim 1. In an automatic railroad switch, pairs of track rails merging into a single pair of rails, a pair of switch points associated with the track rails, train trip operating means spaced from the rails for shifting the switch points and other means associated stock for shifting the switch points,rthe train operating means being rendered operable when rolling stock approaches the switch from the swinging ends of the switch points" and including a pair of arms pivoted on a cross tie at adjacent ends with the outer ends disposed adjacent the switch points, longitudinally extending operating rods for the arms operatively engaged therewith and trip lever engaged with the other ends of the rods adapted to be operated by rolling stock to with'the' T3115 and operated by the wheels of rolling able when rolling stock approaches the switch e engaged with the tie bar connecting the switch points for moving the switch points.

3. In an automatic railroad switch, pa rsof track rails merging into a single pair of rails, a pair of switch points associated with the-track rails, the train trip operating means spaced from the rails for shifting the switch points and other means associated with the longitudinally of the track, oper-' rails and operated by the Wheels of rolling stock for shifting the switch points, the train trip operating means being rendered operable when rolling stock approaches the switch from the swinging ends of the'switch points and including a pair of arms pivoted on a cross tie at adjacent ends with the outer ends disposed adjacent the switch points, a pair of link connected operating rods supported on cross ties associated with each arm with one rod of each pair connectedto an arm and trip levers associated with the other ends of the operating rods and a tie bar connecting the swinging ends of the switch points whereby the operationof one arm efcause the arms to move the switch points,

the other means for operating the switch points including a pair'of journalled shafts extending longitudinally of the track, operating means for the shafts including trip arms on the shafts and disposed adjacent the track rails tobe operated by the wheels of rolling stock and arms fixed to the shafts engaged with the tie bar switch 2. Inan automatic railroad switch, pairs of'track rails merging into-a single pair of rails, a pairof switch points associated with the track rails, train trip operating means spaced from the rails for shifting the switch points and other means associated railsand operated by the wheels of rolling stock for shifting the switch points, the train trip operating means being rendered operwith the connecting the points for moving the switch'points.
